A follow up to my in-class commentary..

I have found on Real Clear Politics an excellent global warming article which highlights scientific research and opinions ignored or invalidated by the media. Definitely worth a read, here are some of my favorite excerpts:

"In "An Inconvenient Truth," Gore says that "sea levels worldwide would go up 20
feet." But the group that shared last week's Nobel Prize, the Intergovernmental Panel on Climate Change, says in a hundred years, the oceans might rise 7 to 24 inches."

"[W]hile man's greenhouse gasses may increase warming, it's not certain
that man caused it. The most impressive demonstration in Gore's movie is the big
graph of carbon-dioxide levels, which suggests that carbon levels control
temperature. But the movie doesn't tell you that the carbon increases came after
temperatures rose, hundreds of years later"
